The discussion on the Leica forum has indicated that the flare problem comes from filters that are coated on only one side (the outside) and that the "flare" is not true flare, but a reflection (probably off the surface of the sensor itself) and is present whenever you use filters under certain conditions, on any camera. It's not just a Leica problem. Jorge doesn't get it because he uses Heliopan filters, which are coated on both sides. Apparently the standard B+W IR cut filters are not. There's a variety of ways to take of the problem, actually, and none is too onerous. (For example, you get the reflection when you're shooting into hot lights at high ISOs. You can not do that. Or, you can simply take the filter off, and if you have a lot of IR reflective clothing around, use of Jamie's C1 corrections to remove some of the red. But this, of course, is one shot in a thousand -- how many times are you shooting into hot lights at night with lots of IR and reflective clothing around and you have no choice but to do that?)
As to the possible "trolling," it's not the individual posts that bother me, its the inane repeition of things that have been said a million times already. They don't say it, but the implication is, "Boy, am I glad that I'm smarter than you stupid people because I didn't buy (or returned ) the M8 and bought something good like a Canon, where I don't consider the inherent softness and the blotchy wide-angle corners to be a problem." 😎
